Muon cold nuclear fusion developed mainly in the US and Japan, in conjunction with biological and fossil carbon neutral to the greenhouse effect, could affect the global methanol and carbon cycle to combine two tendencies sought by the man: the preservation of the climate for future generations and sustainable future of the civilisation. Poland has the chance to solve problems occurring in rural areas, reduce national debt and be self-sufficient in terms of energy by 2030, using high energy neutron sources. It has a patent for economically viable production and utilisation of methanol using high energy neutrons.
